LibWasm: Some more performance stuff (#8812)

* wasm: Don't try to print the function results if it traps

* LibWasm: Inline some very hot functions

These are mostly pretty small functions too, and they were about ~10%
of runtime.

* LibWasm+Everywhere: Make the instruction count limit configurable

...and enable it for LibWeb and test-wasm.
Note that `wasm` will not be limited by this.

* LibWasm: Remove a useless use of ScopeGuard

There are no multiple exit paths in that function, so we can just put
the ending logic right at the end of the function instead.
